hi rafael,
I am using a probel sirius multiformat router, everything is genlocked and synced, its just the handful of cameras that i’m having the sync issue with and under normal conditions they are alligned up perfectly, have also already tried other sources at the camera location and the problem disappears, I have today been advised to upgrade the camera firmware, though reading some of the other posts in the forum, could prove tricky, I have also just received a Hamlet monitor scope 9000, which i will be hooking up tomorrow to log any signal errors if there are any.
